T. H. Tse § and L. Pong §

Department of Computer Science, University of Hong Kong, Pokfulam Road, Hong Kong

In this paper, we describe a proposal for formalising data flow diagrams through extended Petri nets. We illustrate the usefulness of the approach by describing how it can be used to analyse the consistency of requirements specifications.

Received July 1986. revised September 1987.
